Pencil Lead Bearing Rule The pencil lead bearing rule is a simple yet effective way to keep your pencils sharp and ready to use at all times. The rule states that you should always store your pencils with the points facing downwards, away from each other. This prevents the graphite cores from rubbing against each other and becoming dull or broken. By following this simple rule, you can extend the life of your pencils and make them last longer. It's also a good idea to keep your pencils in a dry place, as moisture can cause the graphite core to become brittle and prone to breaking. In addition to storing your pencils properly, it's also a good idea to sharpen them regularly. This helps to remove any dull or damaged areas of the pencil lead, which can be difficult to write with. By sharpening your pencils regularly, you can keep them sharp and ready to use for as long as possible.
